There are a lot of ways to get to the pin and none are easy. In calm conditions a big RHBH hyzer over the top is good, in wind you can try a RHFH roller down the middle. Most people play the tunnel shot with a midrange. Don't leave the fairway if you can manage it. The brush in the middle is thick and spikey, and the sides, left and right, are steep hills. If you don't have a clean line for your upshot try sticking it into the crevice on the near side of the rock that the pin is behind, it's an easy putt from there.
